Moses, for example, was not, according to some interpretations of his story, the brash, talkative type who would organize road trips and hold forth in a classroom at Harvard Business School. On the contrary, by today’s standards he was dreadfully timid. He spoke with a stutter and considered himself inarticulate. The book of Numbers describes him as “very meek, above all the men which were upon the face of the earth.” When God first appeared to him in the form of a burning bush, Moses was employed as a shepherd by his father-in-law; he wasn’t even ambitious enough to own his own sheep. And when God revealed to Moses his role as liberator of the Jews, did Moses leap at the opportunity? Send someone else to do it, he said. “Who am I, that I should go to Pharaoh?” he pleaded. “I have never been eloquent. I am slow of speech and tongue.” It was only when God paired him up with his extroverted brother Aaron that Moses agreed to take on the assignment. Moses would be the speechwriter, the behind-the-scenes guy, the Cyrano de Bergerac; Aaron would be the public face of the operation. “It will be as if he were your mouth,” said God, “and as if you were God to him.” Complemented by Aaron, Moses led the Jews from Egypt, provided for them in the desert for the next forty years, and brought the Ten Commandments down from Mount Sinai. And he did all this using strengths that are classically associated with introversion: climbing a mountain in search of wisdom and writing down carefully, on two stone tablets, everything he learned there. We tend to write Moses’ true personality out of the Exodus story. (Cecil B. DeMille’s classic, The Ten Commandments, portrays him as a swashbuckling figure who does all the talking, with no help from Aaron.) We don’t ask why God chose as his prophet a stutterer with a public speaking phobia. But we should. The book of Exodus is short on explication, but its stories suggest that introversion plays yin to the yang of extroversion; that the medium is not always the message; and that people followed Moses because his words were thoughtful, not because he spoke them well.
